Product Details:

The fail-safe digital output module 10201/2/1 has eight 24 Vdc, 550 mA output channels to drive loads up to 13 W. These loads may be resistive (e.g. lamps) or inductive (e.g. solenoids). For inductive loads, a suppression diode is included on each output.

The outputs, including the suppression diodes, are fully tested and may therefore be used for fail-safe applications. Within the configured process safety time, the outputs are tested for:

• ability to de-energize, • ability to de-energize the group (via secondary means),

• crosstalk between outputs, and

• functioning of the suppression diodes

The outputs are split into two groups of four outputs each. Each group has its own secondary means of de-energization. This increases the shutdown selectivity in case of a channel failure. The secondary means of de-energization enables the watchdog and/or the processor to de-energize the outputs, irrespective of the result of the application function.
